No , not erythrops.It actually was at least partly a trick question, sorry about that, but it is Pseudojuloides sp 1. Not officially described, but recognized as a unique species within the cerasinus complex
Notice where the horizontal striping begins, well after the pectoral fins.
Now in the true cerasinus from Hawaii, the horizontal striping begins directly after the gill cover, the facial striping is only one stripe, and the colors are brighter.
The Indo cerasinus is nearly identical to the Hawaiian, except he has 2 stripes in the face.
In xanthomos the coloring is very similar to sp 1, but the horizontal striping ends soon after the pectorals, which is where sp 1 striping begins.
And kaleidos has darker coloring above the striping, with a purple stripe along the base of the dorsal, and the striping runs the length of the body like cerasinus.
The other guesses are in the severnsi complex, except for argyreogaster, which as of now is in its own complex.
